Application. filed November 17, 1919. Serial No. 338,750.

.1 '0 chi whom it may concern:

lie it known that I, has T. Swin'rz, a citizen of the United. States, residing at Indianapolis, in the county oi? Marion and Fltatc of Indiana, have invented certainnew and useful Improvements in Switchboardfdupports. of which the following is a specilication. y

This invention relates to. supports, more especially to a support for switch. boards, and has among its objects the production of a support which will allow a switch board slate to be easily inserted into the support, which will securely hold the slate in place, and. which can be made at a-low cost.

lrlitherto such switch supports were constructed with a groove formed on the inner surface of the upright and horizontal arms at the support. This groove was of such a width that the switch board ate fitted within the same and was held thereby. The pat terns used for forming the mold for the casting of such supports were necessarily complicated on account of. the necessity for forming cores for the groove, and the support was of considerable thickness, much greater than that necessary to support the.

slate, all oi which increased the cost of such sl'lpports.

By my invention 1 obviate the necessity of making relatively complicated patterns and am enabled to reduce the width and consequentlythe weight of the support to a large .1 (sometimes as much as one-hali). In .y'ng the objects of my invention into effeet 1 form a support without a groove and of a width generally about that of the slate to h s supported; apertures are formed along tee inner surface of the supporting arms and spools are inserted. in such apertures. lllz-rnges on the spools serve to hold the slate in place. i

deterring to the accompanying drawings forming a part hereof and in which similar reference characters denote similar parts,

Figure 1, illustrates a front elevation of my improved switch board support showing a slate in place,

Fig. 2, an end elevation thereof,and

Fig. 8, a section taken as indicated in Fig. l.

The support 1, which holds the switch hoard slate 2, is formed with a pedestal 3. From the upper endof the support, substantially horizontal arms l extend in opposite Specification of Letters Patent.

Patented Nov.23, 1 920.

directions and on the ends of such horizontal armset are formed vertical arms 5. The in nor surface of the support formed by such horizontal and vertical arms is of a shape suitable for the reception of the slate to be supported, which in this case is rectangular.

T he inner surfaces of the arms are smooth and a plurality ofobli no holes or apertures 6 formed in any suit-t le manner, are provided at suitably spaced points.

lnto such holes are fitted the shanks 7 of spools having flanges 8 fixed to the ends thereof. The holes 6 and shanks 7 are so proportioned that they fit each other snugly, the shanks being of such length that the flanges 8 make close contact with the arms 5. In assembling a switch board,spools are first inserted into their holes and the slate slid into place as usual, the flanges and. the spool gripping the arms 5 and holding the slate 2 l ing supported in securely fixed relation to the arms.

Although I have described a specific embodiment of my invention wherein. a switch board plate is supported on a suitable pedestal,'1ny invention should not be limited to such specific example, since it is obvious th at other suitable members may be supported by such an arrangement. The arms need not be horizontal. and vertical but may have any inclination desired. The inner surfaces of the supporting arms need not necessarily form right angles, as shown in Fig. 1, nor need the member to be supported be rectangular; These and other changes which may he made in the various details, I consider to be embraced in my invention.

Having thus iliully described my said invention, what ll claim new and. desire to secure by Letters l-atent, l

l. A. switch hoard support comprising supporting arms, obliquely formed apertures therein, and spool members adapted to be inserted in said apertures to securely hold a switch board slate on said arms.

2. A switch board support comprising sup porting arms, apertures therein, and spool members comprising shanks and flanges adaptedto be inserted in said apertures to .hold the switch board slate on said arms,

said shanks fitting into said apertures, and said flanges contact-mg with the surfaces of said arms and of-said slate.

4. A support comprising an arm, an aperture thereln, a spool 111 said aperture and flanges on said spool adapted to grip said arm and to hold the member to be supported in fixed relation to said arm.

In witness whereof, I have hereunto set 10 IRA T. smwrz. LL.
